As far as I remember, several people tried several solutions that were discussed in the forum. Personally, I implemented a different version, a more complicated solution. This involves more work and may be alarming for those who do not like DIY. If my memory serves me correctly, I read it on the F5NPV website, which worked for me. By the way, v2 started with a mechanical defect, which was fixed by the manufacturer. Mounting the IRFZ24 to the heatsink was problematic.?
